From Time:

After enjoying the 78-to-22 confirmation breeze for Chief Justice John Roberts, congressional Republicans are now sweating the Miers vote count and tell TIME that it could be as low as 52—embarrassing but still good enough for a lifetime appointment. Lawmakers and staff contend that during her first round of courtesy calls, Miers had anything but a commanding presence, looking more like a prom date next to the confident Senators. Republicans said she seemed unwilling or unable to answer questions about whether she viewed particular cases as important precedents and said she offered little beyond banal chatter.
